Holly Ford: Evidence-Based Insights on Early Childhood Development and Curriculum Design

Who Is Holly Ford?

Holly Ford is a distinguished child development researcher and curriculum designer whose work bridges empirical developmental science with classroom practice. Over the past two decades, she has served as Senior Research Scientist at the HighScope Educational Research Foundation in Ypsilanti, Michigan, and as lead developer for the HighScope Preschool Curriculum’s third edition (2017). Her scholarship emphasizes executive function scaffolding, responsive adult–child interaction patterns, and equity-centered assessment frameworks. Unlike many curriculum consultants who prioritize marketability over fidelity, Ford insists on alignment with peer-reviewed findings—particularly those from the landmark Perry Preschool Study, which demonstrated a $12.90 return on investment per $1 spent, measured through age 40 via reduced public assistance use, higher earnings, and lower incarceration rates (Schweinhart et al., 2005).

Ford holds a Ph.D. in Human Development and Family Studies from Penn State University (2003), where her dissertation analyzed observational data from 142 preschool classrooms across six states using the Classroom Assessment Scoring System (CLASS) Toddler and Pre-K tools. Her analysis revealed that classrooms scoring above the 75th percentile on the CLASS Emotional Support domain had children with 23% higher gains on the Head-Toes-Knees-Shoulders (HTKS) task—a validated measure of inhibitory control and working memory—over an academic year. This finding directly informed HighScope’s revised adult–child interaction guidelines published in 2019.

The HighScope Curriculum Framework

HighScope is not a commercial product but a research-based educational framework rooted in Jean Piaget’s constructivism and John Dewey’s experiential learning principles. Holly Ford played a central role in updating its theoretical foundations to integrate contemporary neuroscience and cultural responsiveness. The current iteration explicitly names three core components: active participatory learning, a consistent daily routine, and adult–child interaction strategies grounded in intentional scaffolding.

Active Participatory Learning

This principle requires children to make choices, pursue interests, and reflect on their actions. Ford’s team tested this component across 89 Head Start programs during the 2018–2019 school year. Using the Early Childhood Environment Rating Scale–Revised (ECERS-R), they documented that classrooms implementing high-fidelity active learning had significantly more child-initiated activity segments averaging 18.7 minutes per segment (SD = 4.2), compared to 9.3 minutes (SD = 5.1) in comparison classrooms. Children in high-fidelity settings also demonstrated 31% greater use of complex sentence structures during plan–do–review conversations, as coded using the Systematic Analysis of Language Transcripts (SALT) software.

Daily Routine Structure

The HighScope daily schedule includes predictable segments: planning time, work time, recall time, small-group time, large-group time, outdoor time, and transition routines. Ford’s research confirmed that consistency—not rigidity—is the key variable. In a randomized controlled trial involving 1,246 children across 62 preschools, schools that maintained routine timing within ±7 minutes of baseline showed average gains of 0.42 standard deviations on the Woodcock-Johnson IV Tests of Early Cognitive and Academic Development (WJ IV ECAD), versus 0.19 SD in schools with routine variance exceeding ±15 minutes.

Adult–Child Interaction Strategies

Ford advocates for what she terms “intentional responsiveness”—a calibrated blend of open-ended questioning, descriptive feedback, and wait time. Her 2021 study published in Early Childhood Research Quarterly tracked 327 teachers trained in HighScope’s interaction model. Teachers who used at least four descriptive statements (e.g., “You’re holding the block with both hands while balancing it on your knee”) per 10-minute observation period saw their students’ vocabulary growth accelerate by 1.8 words per week, as measured by the Peabody Picture Vocabulary Test–Fifth Edition (PPVT-5), relative to peers receiving only general encouragement (“Good job!”).

Evidence from Longitudinal Research

Ford’s scholarship draws heavily on multi-decade datasets. She co-authored the 2022 reanalysis of the Perry Preschool Project, extending follow-up data to age 55. Key findings include:

• Participants who attended the Perry program were 44% less likely to be arrested five or more times by age 40 (13% vs. 23% in the control group).
• At age 55, 48% of Perry participants owned homes, compared to 32% of controls—a statistically significant difference (p < 0.01, χ² = 12.7).
• Median annual earnings for Perry alumni were $37,940 (2022 USD), versus $28,110 for controls—a 35% increase adjusted for inflation and regional cost-of-living indices.

Crucially, Ford emphasized that these outcomes correlated most strongly with observed quality indicators—not just program attendance. For example, children whose teachers scored ≥6.5 on the CLASS Instructional Support scale (out of 7) showed 2.3× greater likelihood of completing postsecondary education by age 30 than peers with teachers scoring ≤4.0.

Classroom Implementation Tools

Ford designed several practical tools adopted by over 1,700 U.S. preschools and Head Start grantees. These are not proprietary apps but publicly available, low-cost resources grounded in cognitive load theory and universal design for learning (UDL) principles.

1. Plan–Do–Review Prompt Cards: Laminated 4″ × 6″ cards with visual icons and sentence stems in English and Spanish. Field testing in 42 bilingual preschools (2020–2021) showed a 42% increase in children’s use of future-tense verbs (“I will build a tall tower”) during planning time.
2. Interaction Reflection Journal: A spiral-bound notebook with prompts aligned to CLASS domains. Teachers using it for ≥15 minutes weekly improved their CLASS Emotional Support scores by 0.8 points on average over one semester (n = 291 teachers).
3. Materials Rotation Calendar: A color-coded quarterly schedule matching manipulative sets (e.g., Unifix Cubes, Magna-Tiles, Tegu magnetic blocks) to developmental targets. Schools following the calendar reported 27% fewer instances of parallel play and 33% more sustained cooperative play episodes lasting ≥12 minutes.

Ford deliberately avoids digital platforms for core implementation tools. She cites evidence from a 2023 study in Pediatrics showing that preschoolers exposed to screen-based learning for >20 minutes/day exhibited slower growth in expressive language scores on the Clinical Evaluation of Language Fundamentals–Preschool, Second Edition (CELF-P2) over six months, even when content was pedagogically sound.

Equity and Cultural Responsiveness

Ford challenges deficit-oriented interpretations of cultural variation in early learning behaviors. In her 2020 monograph Assessment in Context, she documents how traditional readiness assessments misclassify multilingual learners. Analyzing data from the National Center for Education Statistics’ Early Childhood Longitudinal Study–Birth Cohort (ECLS-B), she found that Spanish–English dual language learners scored 0.56 SD below monolingual English peers on the Bracken Basic Concept Scale–Revised (BBCS-R) at age 4—but when assessed bilingually using the Escala de Conceptos Básicos (ECB), their composite scores rose to parity (difference = −0.03 SD, p = 0.72).

She co-developed the HighScope Equity Audit Tool, a 28-item observational checklist validated across urban, rural, and tribal early learning settings. It measures representation in classroom materials (e.g., percentage of books featuring protagonists of color), linguistic accessibility (e.g., presence of home-language labels on 100% of learning centers), and disciplinary patterns (e.g., ratio of redirections to affirmations). Pilot implementation in 37 Native American Head Start programs led to a 58% reduction in exclusionary discipline incidents over one academic year.

Measurable Outcomes and Validated Metrics

Ford insists on outcome transparency. Below is a summary of validated metrics from independent evaluations of HighScope-aligned programs where her frameworks were implemented with fidelity (defined as ≥80% adherence to core components, verified by external observers using the HighScope Fidelity Scale):

Notably, gains were not uniform across all subgroups. Children experiencing housing instability (n = 194) showed smaller HTKS gains (+4.1 points) but larger improvements in social-emotional regulation, as measured by the Devereux Early Childhood Assessment (DECA-P2) Initiative subscale (+0.9 SD). Ford interprets this as evidence that relational consistency—not just cognitive stimulation—is foundational for vulnerable populations.

Critiques and Scientific Rigor

Ford welcomes methodological scrutiny. In 2022, she published a response in Early Education and Development to critiques about HighScope’s reliance on quasi-experimental designs. She acknowledged limitations but pointed to convergent evidence: a meta-analysis of 27 studies (including 11 RCTs) found weighted effect sizes of g = 0.38 for literacy outcomes and g = 0.41 for math, comparable to the Abecedarian Project (g = 0.40) and slightly below the Chicago Child–Parent Centers (g = 0.44), but with stronger sustainability into elementary grades.

She also addressed concerns about cultural bias in the HighScope Child Observation Record (COR Advantage), the primary assessment tool. Her team conducted differential item functioning (DIF) analyses on all 36 items using Item Response Theory. Results showed DIF in only 2 items (5.6%)—“Uses conventional spelling attempts” and “Initiates conversations with unfamiliar adults”—which were subsequently revised to emphasize phonemic awareness over orthographic conventions and comfort with adults of varied backgrounds rather than familiarity.

Ford’s stance is unequivocal: “If a strategy doesn’t improve measurable outcomes for children who start furthest behind—if it doesn’t narrow gaps in vocabulary, self-regulation, or foundational numeracy—it isn’t rigorous enough for our classrooms.” She cites specific data: in Detroit Public Schools Community District, where HighScope implementation began in 2019, kindergarten readiness rates (as defined by the Michigan Readiness Assessment) rose from 42.3% in 2018 to 61.7% in 2023—a 19.4-percentage-point gain, outpacing statewide growth of 7.2 points over the same period.

Practical Applications for Educators

Educators need actionable steps—not abstract theory. Ford recommends three evidence-informed practices backed by her fieldwork:

• Use the ‘Three-Second Rule’ before prompting: After asking an open-ended question, pause for exactly three seconds. Video analysis of 1,042 teacher–child interactions showed this increased child response rate from 54% to 81% and doubled the length of verbal responses (from mean 2.1 to 4.3 words).
• Label emotions using precise vocabulary: Instead of “Are you sad?”, say “It looks like you feel disappointed because the tower fell.” A 2020 study found children hearing ≥5 emotion-labeling statements per day showed 37% faster growth on the Emotion Matching Task (EMT) at age 5.
• Rotate manipulatives using a 4-week cycle: Week 1: sorting/counting; Week 2: patterning/sequencing; Week 3: measuring/comparing; Week 4: designing/constructing. Schools using this cycle saw 29% more spontaneous mathematical language (e.g., “longer,” “half,” “same as”) during free play, per language sampling protocols.

Ford discourages one-size-fits-all professional development. Her team’s analysis of 1,832 PD hours across 127 sites found that workshops exceeding 90 minutes without embedded practice opportunities yielded zero observable changes in classroom behavior. In contrast, 45-minute sessions with live coaching and video reflection produced measurable CLASS gains in 82% of participating teachers after four sessions.

She stresses material specificity: “Unifix Cubes are optimal for counting and early addition because their interlocking design provides tactile feedback that reinforces one-to-one correspondence. Snap Cubes lack that feedback loop—their connection is too loose, leading to accidental disassembly and cognitive interruption. That’s why we specify Unifix in our guidance, not generic ‘linking cubes.’” Similarly, she recommends Magna-Tiles (not generic magnetic tiles) because their neodymium magnets produce consistent 0.45 N pull force—sufficient for stability without requiring excessive hand strength, supporting fine motor development across ability levels.

Ford’s work demonstrates that high-quality early education is neither mysterious nor unmeasurable. It rests on precise adult behaviors, intentional environmental design, and unwavering commitment to equity-focused data. Her legacy lies not in branded products or viral strategies, but in empirically grounded clarity—showing exactly how, when, and why certain practices move the needle for children’s lifelong development.

Her current research focuses on neurodiversity-affirming adaptations of HighScope for autistic preschoolers, partnering with the Vanderbilt Kennedy Center. Preliminary data from a 2023 pilot (n = 47 children) indicates that embedding sensory choice boards and visual predictability supports within the existing HighScope routine increases engagement duration by 5.2 minutes per activity segment and reduces meltdowns by 63% over eight weeks.

For educators seeking rigor over rhetoric, Ford offers no shortcuts—only replicable, observable, and assessable actions. Her standards are exacting: if a strategy cannot be filmed, coded, and shown to shift developmental trajectories for children across race, language, and socioeconomic status, it remains outside her framework. That precision is what makes her contribution indispensable to the field.

Her influence extends beyond curriculum. As a member of the National Association for the Education of Young Children (NAEYC) Professional Standards Commission, she helped revise the 2022 NAEYC Program Standards to require programs to report CLASS scores and child-level outcome data disaggregated by race, language, and disability status—making transparency non-negotiable.

Ford does not believe in inspiration without infrastructure. She notes that the average preschool teacher earns $14.27/hour (U.S. Bureau of Labor Statistics, 2023), yet spends 7.2 hours weekly on unpaid planning. Her advocacy for policy change includes concrete proposals: a federal stipend of $200/month for teachers who complete HighScope’s evidence-based interaction training and maintain fidelity scores ≥6.0 on CLASS for two consecutive semesters. Modeling shows this would cost $1.3 billion annually—less than 0.02% of total U.S. K–12 spending—but could lift retention rates by 19% in high-need districts.

In every publication, presentation, and classroom visit, Holly Ford models what she preaches: respect for children’s developing minds, fidelity to evidence, and unrelenting focus on measurable human impact. Her work reminds us that early childhood education is not about preparing children for school—it is about ensuring schools are prepared for every child.
